Influence of fat percentage on the strength of men trained
Abstract
Introduction: Weight, lean body mass, and body fat can all influence a person's maximum strength. This information can be based on the physical structure that the individual develops and maintains their physical abilities to perform an activity. Objective: To analyze if there is influence of the amount of body fat on the force. Methodology: Twenty men were divided into two groups: Group 1 (G1: 10 lean) and Group 2 (G2: 10 obese). The anthropometric tests were performed to evaluate the percentage of fat and the test of 1RM in bench press and LegPress for the analysis of maximum strength. Statistical analysis was performed using the Student's t-test for independent samples, considering p <0.05. Significant values were observed in the obese group as maximum force in LegPress (23%, p <0.05), Pearson correlation in relation to weight vs 1RM (P <0.05) and fat (60%, p <0.05), and a higher amount of lean mass (43%, p <0.05). Conclusion: In this study it can be observed that a higher amount of body weight leads to a greater amount of lean body fat mass, which significantly influences the maximum force.
